Good powder for skiing. Watch for localized slabs sitting over the Oct. 26 crust and facets. It is still possible to trigger large avalanches in more aggressive terrain. Very limited observations as of yet in the Little Yoho region.
Weather Forecast
Cold, clear weather for a few days.
Snowpack Summary
25-40cm of recent snow with variable wind effect overlies a faceted snowpack 60-80 cm deep at treeline and up to 150cm on the Icefields. The Oct. 26 crust and facets sit roughly 30 cm above the ground up to 2800m on shady aspects, and above 2800m on solar aspects. This crust has been dormant recently, producing only hard results in field tests.
Avalanche Summary
no new avalanches reported
Confidence
Due to the number of field observations
Problems
Deep Persistent Slabs
Deep Persistent Slab avalanches are the release of a thick cohesive layer of hard snow (a slab), when the bond breaks between the slab and an underlying persistent weak layer deep in the snowpack. The most common persistent weak layers involved in deep, persistent slabs are depth hoar or facets surrounding a deeply buried crust. Deep Persistent Slabs are typically hard to trigger, are very destructive and dangerous due to the large mass of snow involved, and can persist for months once developed. They are often triggered from areas where the snow is shallow and weak, and are particularly difficult to forecast for and manage.
